Answer :
let the breadth of the rectangle is x
length of the rectangle is 3x
area = length * breadth
675 = 3x*x
225 = x²
x = 15 or -15
breadth can't be negative hence
breadth = 15 cm.
length of the rectangle is 3x
area = length * breadth
675 = 3x*x
225 = x²
x = 15 or -15
breadth can't be negative hence
breadth = 15 cm.
Let Breadth of the rectangle be x
and its Length is 3x
Its
Area = Length*Breadth
=(x*3x) centimeter square
=(3x^2) Cm square
But according To problem,
area is 675 cm square
equating,
675=3x^2
x^2=675/3
x^2=225
x= 15 Cm (square root of 225)
since negative sign is not taken as its measurement of breadth.
Hence, Breadth of the rectangle is 15 Cm.
and its Length is 3x
Its

=(x*3x) centimeter square
=(3x^2) Cm square

Hence, Breadth of the rectangle is 15 Cm.
